2 Claims. (Cl. 259131) The invention relates to beaters and mixers of the type employed for beating eggs, mixing mayonnaise, whipping cream, and for other like purposes. It has for one of its main objects to provide a device with which these operations may be performed in much less time and with much less labor than with the devicesnow on the market. Another object is to provide means on the device for preventing the rotating heaters from coming in contact with the sides of the bowl or vessel in which the device may be used. A further object is to provide a device of strong but light construction, having no parts readily broken or apt to wear out, and which can be manufactured at a comparatively low cost.

These and various other objects and advantages will be readily understood from the following description and from the accompanying drawing of a preferred embodiment of the invention in which, however, modifications may be made without departing from the scope of the appended claims. In the drawing Fig. 1 is a side elevation of the invention,

Fig. 2 a front elevation of the same, and

Fig. 3 a cross-sectional View taken on line -33 of Fig. 2.

While I am. aware that the prior art discloses gear-driven beaters and mixers employing dashers, the present invention resides principally in the novel construction and arrangement of the dashers themselves and in the arrangement of the means for increasing the speed of the rotating dashers.

Referring now to all the views, simultaneously, the device consists of a body member which forms a frame for the gears employed. The

upper part 11 of the body member is narrowed down and provided with a handle 12 by which the device is steadied when in use. An aperture 13 is formed in the body member and a spur gear 14 is mounted in this aperture, as is also a pinion 15 which meshes with the spur gear. The

gear 14 is secured on a shaft 16, one end of r which is bent to form a crank 17 on which the handle 18 is rotatingly mounted. The pinion is secured on a shaft 19 on which shaft two bevel gears 26 and 21 are also pinned.

A frame 22 is supported on two downwardly extending lugs 23 and 24 which are formed on the lower end of the body member. This frame, which is of the shape plainly shown in Fig. 1, supports the rotating dashers 25 and 26. Bevel pinions 27 and 28 are secured on the upper ends of the dashers and the dashers, together with the bevel pinions, rotate on pins 29 and 30 see cured, respectively, in the body member and the frame 22. The bevel pinions mesh with the bevel gears 20 and 21. I

The frame. 22 is provided with two curved, sidewardly extending arms 31 and 32 between which the dashers rotate. Two rings 33 and 34 are rigidly mounted on the pins 30 so that they will not turn. They are preferably placed at right angles to the arms 31 and 32, as plainly shown in Fig. 3. v n

The device operates in the following manner. When the crank is turned, the gear train causes the dashers to rotate in the directions indicated by the arrows in Fig. 3, or vice versa. As the materials to be mixed or beaten are forced between the dashers, the stationary rings 33 and 34, and the stationary arms 31 and 32, a thorough mixing or beating results; at the same time only the two dashers 25 and 26 are rotated. Thus, a

minimum amount of power is-required to turn the crank, and, owing to the high gear ratio of the gear trains, the dashers will rotate at high speed, even when the crank is turned slowly. As the arms 31 and 32 extend outside of the circles described by the dashers, the latter cannot contact with the sides of the vessel in which the device is used. These arms, together with the frame 22, besides aiding in the mixture and beat-' ing, constitute dasher guards.

While I have described and illustrated a gear 1 train of a certain construction, it is evident that many other arrangements of gears might be employed. q

Having described my invention and its advanby Letters Patent is:

1. In a device of the class described a body I arms formed onthe dasher frame at right, angle thereto; stationary members mounted within each dasher substantially parallel with the dasher frame; the dasher frame, the curved arms and dashers in the operation of the device;- all of said parts being of curved cross-section to enable them to pass each other in close proximity to further aid in the operation; gears mounted; on 110 the upper ends of the dashers; and a train 'of tages, what I claim as new and wish to protect' the body member; a pair of upwardly-curved 1.105 the stationary members all co-a'cting with the the body member; a pair of upwardly-curved arms formed on the dasher frame at right angle thereto; stationary members mounted within each dasher substantially parallel with'the dasher frame; the dasher frame, .the curved arms and the stationary members all co-acting with the dashers in the operation of the device; gears mounted on the upper ends of the dashers; and a train of gears connecting these gears with the gear secured on the crank shaft.
